The compatibility of sensor functionality requires periodic calibration in an accredited laboratory. The calibration process involves temporarily disconnecting the sensor from operation, performing necessary preparations, and determining the sensor's condition. As a solution to improving the calibration process, the use of mesh networks is presented to avoid disconnecting sensors from active states. Using ZigBee technology, all sensors are represented through nodes with specific functions in the network. Information exchange occurs wirelessly among all nodes in the network, which are involved in communication with the main node (gateway). The main node serves the function of storing and processing data based on specified standards. To gain complete control over the system, observed state changes are stored in the main node's memory, which communicates with all nodes in the network during its operation. Deviations from reference sensor values are determined based on collected parameters from other nodes in the wireless sensor network. To expedite network operation, there is a need to categorize nodes into different types. Definitions of all node types are stored in a dynamic state table, with parameters defining the node type and its state. To facilitate access to all defined nodes from the dynamic state table, node types, in addition to the main node, are divided into reference and regular nodes. Reference nodes in the network do not have a constant role, and their role is separate from regular nodes to expedite communication and parameter retrieval for necessary analyses. Retrieved parameters from the state table are included in the comparison and analysis process based on node type. Obtaining results enables the identification of deviations, issues during operation, and the correctness of retrieved data compared to reference sensors.
